AI Technical Summary

Technical Problem

Conventional display devices have low aperture ratios due to structures separating sub-pixels, which hinder the realization of high resolution.

Method used

A display device design that includes a substrate with sub-pixels containing first and second transistors, first and second light-emitting elements, and a bank layer with overhang structures, allowing for increased image display area by forming light-emitting elements between and on the bank layer, and utilizing a patterned light-emitting layer to simplify manufacturing.

Benefits of technology

The design enhances aperture ratio and enables high resolution by increasing the actual image display area, while simplifying the manufacturing process and reducing power consumption.

Abstract

To provide a display apparatus with improved aperture ratio and definition.SOLUTION: A display apparatus in an example includes a substrate including a plurality of subpixels, a first light-emitting element disposed in each of the subpixels, a first transistor disposed in each of the subpixels and driving the first light-emitting element, a second light-emitting element disposed between the adjacent subpixels among the plurality of subpixels, and a second transistor disposed in each of the subpixels and driving the second light-emitting element. The gap between the substrate and the second light-emitting element is larger than the gap between the first light-emitting element and the substrate.SELECTED DRAWING: Figure 5
